This invention relates to pipe presses, and the primary object o fftheih Yention is to provide a geared mechanism p for -oper2iting. the clay lunger or follower oi the press so that lt-he stifekeoif the phi ng'er will be positive pO'r'dinari-ly the pl ifiger is oper'ated Lby vsteam or air..- jThe play oflisjconsiderebie Tesistenceto the plii-ngegend si c e both,

Prior to {myj invention it has been recognized thet it is desirable to provide a, plunger with some sort of geared mechanism so that a; posigive action couldbe imparted to the piuirger,

One edge of the brr 22 carries rack teeth which are eirgrg'ed by pinion '31 on the shaft 32 mounted in bearifigs33, 34 and 35 cariied by t-he base The pinion 31 is betweeii thQbem-ingsy and and there is a gear 36 oh the strait 32 between the bearings 34 and 375., The gear '36 is driven by a piiiion'37oi1 shaft 38 mounted .in bearings 39 on base 3'.- On shaft 38 there is '21 brake am-m 40 adapted to be engagedby a braike 'ba-iid 41*1'1; an a propriate metiiliersi'mi'lar ordinary "ake bfa'nd andrdi'ii'm eoinbii-iizitioiisfl brake drliiri is fastto" the shaft 38 and it carries a cone clutch 42 edapted'to be engaged by i socket member -43 loose on "shaft 38; end having gear teeth 44-ineshing with 3 pmion *45 oii the drive shaft- 6f the-electric motor 46.

Y Assuming th t v rota-ting and. it is, desired to operate the plunger through themedium of the ge'armg swung to turn the piston 52 to cause the panding spring. 47. There is a sleeve 48 extending over the end of the shaft 38, the sleeve 48 also receiving a shaft 49 which may have slight longitudinal movement with respect to the sleeve, but which may beheld against rotative movement with respect to the sleeve by the lugs or pins 50. The shaft 49 and the sleeve 48 may be urged toward the member 44 by a screw 51 carrying a pinion 52 engaged by the teeth of the gear segment53, the segment being operthe motor constantly consisting of the pinion'37, gear 36 pinion 31 and rack bar 22, the. rod 54 will be screw 51 to force the shaft 49 and sleeve 48 toward the clutch member 4344, to

cause the cone 42 to engage in a socket Thenthe gear will begin to operate. If it 1s desired tovstop 'the plunger at any P011113.

I the brake willbe' applied. The motor 461s areversing motor-supplied with current in the usual way, and I have therefore, provided a reversing switch 55 in a circuit consisting of the conductors 56 and 57 so that the gear maybe operated to force the plunger downwardly or to retract .it 4 upwardly. The bottom of the cylinder 27 is provided with the usual dies 58 and 5 9 to unnecessary.
